McCaskill is always under estimated. Too early to count out Tester and Donnelly. Too early to say we will absolutely gain Nevada or have a chance in Arizona.
That being said, even as I have strong beliefs against making hasty predictions years in advance, I am sure the GOP will hold the Senate in 2018.
House will be interesting.
I am not exactly old, I am 28. But I am old enough to have seen several election cycles, I feel like our younger posters get caught up with the most recent general election results. Literally two months ago, people were saying Democrats would always win the Presidency due to firewall and GOP will always win midterms due to turnout.
We saw how the former turned out, we just have to wait to see how the latter will turn out.
This.
